The editor of the magazine JotDown, known by the (false) name of Mar de Marchis, caused a revolution in the Spanish press not only with her publication but by becoming friends or a confidante to numerous figures with media power at the time without leaving home, due to agoraphobia and depression. The journalist and correspondent for El País Daniel Verdú wanted to explain who was really hiding behind this pseudonym, but, above all, to show what the media landscape was like a decade ago, which was sensitive to this gale of ideas, shamelessness, mystery, brilliance, and deception that was De Marchis.
